一、通过化学课堂教学渗透环保知识要充分挖掘和利用教材中的环保知识内容,采取多媒体手段,让学生增长环保知识。例如对于高一的硫酸工业制法的教学,在讲SO2尾气的污染时,让学生看了酸雨危害的录像,还让学生做了将SO2回收制取H2SO4及液态SO2的练习题。在讲氮族元素这一章时,涉及氮在自然界
First, infiltration of environmental knowledge through chemistry classroom teaching To fully tap and use the contents of environmental knowledge in teaching materials, take a multi-media approach to enable students to increase environmental knowledge. For example, for the teaching of a high-grade sulfuric acid process, students were asked to read a video of the acid rain hazard while talking about SO2 tail gas pollution. Students were also allowed to recycle SO2 for H2SO4 and liquid SO2 exercises. In talking about the nitrogen group this chapter deals with nitrogen in nature
